HW: Write up the solutions and turn in for grading on M Nov 10: 3.6: the two problems below:
A. Find the critical points of the scalar field f(x,y,z)=(x+y-z)^2+y^2+z^2 and use the eigenvalues of the Hessian matrix to decide if these points are max, min, saddle.

Final examination info: You are allowed to bring and use one page (front and back) with your own notes. Here is a Review Guide. Please check the Final Exam Schedule.
I will be available on Friday Dec. 12, from 11 a.m. to noon if you want to see your graded final exam. However, I hope to have everything ready by Thursday, and if so, I will post here a time when I will be in my office on Thursday too.
